Against the club he was all set to join from Crystal Palace before Arsenal's August interention, Eze hit a first hat-trick as the Gunners thumped Spurs on the night.
Eze remarked afterwards: "That is crazy. Special day man. Special day for me, my family.
"I don't think I could've ever dreamt of it. This is more special than that. I can only thank God. Special day, man.
"We were prepared for whatever set up they were coming with because of the diligence of our staff. Huge credit to them. And of course the players in our team, the ability, the talent, from whatever angle we're threatening to score goals.
"Good performance, good three points and a special day.
"I probably should've scored four to be honest. I'm always trying to score, always trying to take my chances. It's important to be relentless.
"We're focused on ourselves, we're focused on putting in our work every day. It's not by chance that we perform like this."
On the favourite of his three goals, Eze added: "They are all good. Maybe the second one. That was my favourite. All of them are good for me because I have been working on the process to get in that position so that's good again."
